Volatile organic compounds (VOCs) are one of the main sources of air pollution, which are of wide concern because of their toxicity and serious threat to the environment and human health. Catalytic oxidation has been proven to be a promising and effective technology for VOCs abatement in the presence of heat or light. As environmentally friendly and low-cost materials, manganese-based oxides are the most competitive and promising candidates for the catalytic degradation of VOCs in thermocatalysis or photo/thermocatalysis. This article summarizes the research and development on various manganese-based oxide catalysts, with emphasis on their thermocatalytic and photo/thermocatalytic purification of VOCs in recent years in detail. Single manganese oxides, manganese-based oxide composites, as well as improving strategies such as morphology regulation, heterojunction engineering, and surface decoration by metal doping or universal acid treatment are reviewed. Besides, manganese-based monoliths for practical VOCs abatementare also discussed. Meanwhile, relevant catalytic mechanisms are also summarized. Finally, the existing problems and prospect of manganese-based oxide catalysts for catalyzing combustion of VOCs are proposed.

锰基氧化物催化剂上VOCs热催化和光/热催化氧化的最新进展

挥发性有机化合物（VOC）是空气污染的主要来源之一，由于其毒性以及对环境和人类健康的严重威胁，因此受到广泛关注。事实证明，催化氧化是一种在存在热或光的情况下减少VOC的有前途和有效的技术。作为环保和低成本的材料，锰基氧化物是热催化或光/热催化中VOC催化降解的最有竞争力和最有希望的候选者。本文总结了近年来各种锰基氧化物催化剂的研究和发展，重点是它们的VOC的热催化和光/热催化纯化。单一的锰氧化物，锰基氧化物复合材料，以及诸如形态调节等改进策略，综述了异质结工程以及通过金属掺杂或通用酸处理进行的表面装饰。此外，还讨论了用于实际VOC减排的锰基整体材料。同时，还总结了相关的催化机理。最后，提出了锰基氧化物催化剂催化VOCs燃烧存在的问题和展望。
